Examples being "Bae" making into the human language. As well as the over one hundred words literally made up by Shakespear to suit his needs.
If they're made up, I'm not sure that is the same thing as changing the definition of a word already in existence.
Though you can probably add to the meaning of the word. There's a reason why many English words have 2+ meanings, or mean different things in different situations.
